Barium strontium aluminosilicate glasses with additions of lanthanum oxide and/or zinc oxide are potential sealing glasses for planar solid oxide fuel cells (pSOFCs).

The thermophysical and structural properties of different series of these glasses are being studied to understand their property composition relationships.

Thermal analysis and dilatometry are being used to assess the thermal properties of the glasses, while the glass structure is being studied by Raman and Fourier transform infrared spectroscopies.

High temperature mechanical test measurements and electrical measurements are also being undertaken. This talk focuses on how these properties vary with the compositions of these glasses.
